Speed performance
Your page's performance can be slowed down by a large DOM tree:
SeoChecker shows in a table like the one below the total DOM elements of a page, its maximum DOM depth and its maximum child elements:
SeoChecker notifies pages with DOM trees with a total of nodes more than 1500, a depth major than 32 nodes and a parent node with more than 60 child notes.
Try to not keep unnecessary nodes, spotting them for example loading the page and mark the useful nodes.
Another way is to make your CSS selectors easier.
